I now need not necessarily a huge sound cannon, but only one speaker, which sounds reasonable, without much cost. I have been using this product found. Edifier I was already from before a term, as well as my PC speaker set which comes and then has surprised me very pleasantly. Edifier is from my experiences for some unusual design and good sound quality at a low price.
All in one - the sound quality is very good. You can have a lot of bass, when you stand on it, but without the sound very pleasant. I now hear it is not necessarily music or bombastic Blurays, but for my purposes, this system is perfectly adequate.
A very annoying quirk was the thing though. It often happens that when you have done with the remote control even louder or quieter, after a while the volume of itself gradually goes into the last used direction. You can turn it off if you're single presses the other direction, the volume while strangely still goes one step in the current direction. It is totally annoying and would be for me definitely the whole system to send back, but you can work around very easily by, after you select the desired volume, the system switches briefly off and on reason. The remote control is a minimal effort and I can live with it. For some, this is likely to have a deterrent effect.
